I've searched to see if any one else addressed this and couldn't find anything.

After 2 missions and 1 random encounter weapon familiarity for all weapons remains 0.

Couldn't find any specifics concerning how this stat improves in the manual. Does it simply increase through usage of the weapon or is there other criteria?

If not, I wondering if I have a glitch than anyone else had.

I'm running through GOG Galaxy and having manually installed any patches.

Thanks

Oh boy, it's been a while since I played Silent Storm, but I do recall a bug with weapon familiarity. Either it doesn't work at all, or it reset when you change weapons, or something like that. Whichever it is, it wasn't a stat I relied on. It works properly in Silent Storm Sentinels though, increasing with every use.

Thanks for responding. I've concluded that if it is a bug it's still not important. It's more important to acquire better weapons. I did notice since originally posting that in one case it was "1" rather than "0".

Very minor flaw in a great game though.

Thanks again.

It was so long ago when I played this game last time... Here's what I remember about weapon familiarity

1) Weapon familiarity works only for one specific weapon (not a type). When you begin to use another weapon (same or different type), this stat for previous weapon starts to go down.
2) Some soldiers have perk that boosts weapon familiarization by 100%.
3) Each point of weapon familiarity gives your soldier +1% of aim when they use this weapon. Leveling this stat you can get +10% or higher. Edit: I got 15 weapon familiarization with the Suomi SMG, this might by a maximum.
4) There was a trick in release version of Silent Storm that might be helpful if you want to level up familiarity fast. Your soldier should not just fire, but reload the weapon too. Shoot one round - unload ammo - load ammo. I don't know if it works for patched version.
